Garmin Rally RK210 Dual-Sensing Power Meter
The Garmin Rally RK210 is the most advanced LOOK KEO-compatible power meter pedal available, delivering dual-sided power measurement, a full suite of advanced cycling dynamics, and +/- 1% accuracy in a lightweight carbon build designed for serious road cyclists. Using a reimagined strain gauge and added gyroscope on both pedals, the Rally RK210 captures true left and right power simultaneously — unlocking metrics that single-sided systems simply cannot provide, including left/right power balance, seated versus standing time, power phase, and platform center offset.
These advanced cycling dynamics give road cyclists and coaches the biomechanical detail needed to identify inefficiencies, correct cleat positioning, and optimize pedaling technique over time. Combined with Pedal IQ smart calibration — which monitors temperature changes and other conditions to alert you precisely when calibration is required via compatible Garmin devices — the RK210 ensures your power data remains accurate and trustworthy through every ride, every season, and every condition.
Wrapped in a pro-level all-carbon construction that keeps weight low and durability high, the Rally RK210 is built to perform at the front of the pack. Its rechargeable battery delivers up to 90 hours of ride time per charge, with rapid charging that provides 12 hours of ride time from just 15 minutes plugged in, and a travel mode that conserves battery between sessions. The removable power sensor transfers quickly between Rally 110 and 210 road or off-road pedal bodies (sold separately or as a bundle), making the RK210 a smart, multi-bike investment for LOOK KEO riders with more than one build. Compatible with oval chain rings and fully integrated with compatible Garmin Edge cycling computers and the Garmin Connect app, the RK210 syncs training data automatically to Strava, TrainingPeaks, TrainerRoad, and the Tacx Training app for structured indoor workouts and virtual course exploration. For LOOK KEO cyclists who want the definitive dual-sensing power meter pedal with carbon construction and the full Garmin advanced cycling dynamics feature set, the Rally RK210 stands alone.
